At-Risk Basis Calculator
§465 at-risk rules limit loss deductions to amounts you have economically at risk in the activity. At-risk basis = cash contributed + recourse debt + qualified non-recourse debt (real estate only) − losses already deducted. Losses above this basis are suspended and carry forward. This calculator computes your current at-risk basis.

How the math works
At-risk basis = cash contributed + recourse debt + qualified non-recourse (real estate only) − losses already deducted. You can only deduct losses up to your at-risk basis. Losses above are suspended, carry forward.
Real estate gets a special break: qualified non-recourse debt counts toward at-risk basis even though you're not personally liable. Pure non-recourse debt (other businesses) doesn't qualify.
EveryCalc calculators are designed for fast, practical estimates with transparent inputs and no required account. We use plain formulas, visible assumptions, and related tools so visitors can check the result from more than one angle.
Results are informational only. For financial, tax, legal, medical, construction, or other high-impact decisions, verify the output against primary sources or a qualified professional.

How this calculator works
What this page estimates
This At-Risk Basis Calculator is built to give a quick, browser-based estimate for at-risk basis. §465 at-risk rules limit loss deductions to amounts you have economically at risk in the activity. At-risk basis = cash contributed + recourse debt + qualified non-recourse debt (real estate only) − losses already deducted. Losses above this basis are suspended and carry forward. This calculator computes your current at-risk basis. The inputs stay on the page during normal use, and the result should be treated as an estimate for planning, comparison, or education rather than professional advice.
Calculation approach
The calculator applies the standard relationship implied by the inputs, then formats the answer so it can be checked and reused. For finance tools, the most important step is using consistent units, rates, time periods, and assumptions before comparing the result with another calculator or outside quote.
Example workflow
For example, start with a realistic value you already know, change one input at a time, and watch how the answer moves. That makes it easier to tell whether the result is being driven by the main amount, the rate, the time period, or a unit conversion.
Practical checks
- Use current, real-world numbers when the result affects money, health, tax, or legal decisions.
- Run a low, base, and high case when the inputs are estimates.
- Check the related calculators below when the next decision depends on a different assumption.
How to interpret the at-risk basis result
Best use
Use the result as a planning number for comparing payments, rates, returns, tax reserves, or cash-flow choices before you request a quote or make a commitment.
Cross-check
Compare the answer with the contract, lender estimate, tax form, brokerage statement, payroll record, or invoice that will control the real-world outcome.
Watch for
Do not rely on a single optimistic rate, return, or fee assumption. Money pages work best when you run low, base, and high cases and keep professional advice separate from the estimate.
This page belongs to the Finance calculator library, so the answer should be read in the context of the decision you are modeling rather than as a universal rule.
Before relying on this at-risk basis estimate
Most calculator mistakes come from the inputs, not the arithmetic. Use this short audit before you reuse the answer in a spreadsheet, quote, application, or important conversation.
Confirm source numbers
Match balances, rates, fees, taxes, income, and payment dates against the lender quote, payroll record, tax form, statement, invoice, or contract.
Separate cash flow from total cost
A lower monthly payment can still cost more over time if fees, interest, taxes, or a longer term are hidden in the structure.
Run conservative cases
Test at least one higher-cost or lower-return case before using the output for a purchase, refinance, investment, loan, or tax decision.
Rerun this page when the rate, price, term, fee, tax rule, income, expense, or expected holding period changes.
How to Use
- Enter cash contributed to the activity.
- Enter recourse debt (personally liable) and qualified non-recourse debt (real-estate-secured).
- Enter losses already deducted.
- Read current at-risk basis (your future loss deductibility cap).
Frequently Asked Questions
Recourse vs non-recourse?
Recourse: you're personally liable. Non-recourse: lender's only collateral is the asset. Recourse adds to at-risk basis; non-recourse generally doesn't — except real-estate-secured QNR.
Qualified non-recourse?
Real estate financing from commercial lender (bank, insurance company, GSE) where the lender isn't related to the borrower. Common conventional rental mortgages qualify.
Suspended losses?
Losses above at-risk basis carry forward. They free up when your at-risk basis grows (more cash, more recourse debt) or you dispose of the activity.
